Preheat the oven to 350˚F. Lightly grease a 9×13 inch baking dish and set aside.
In a medium bowl, whisk together all of the ingredients, except the peaches. Gently fold in the diced peaches and pour into the prepared baking dish.
Bake in the preheated oven for 25-30 minutes, or until set in the middle. Cut into squares, and top with yogurt and coconut chips, if desired.
